Looked at the character, didnt do ANY number crunching I will save that for an actual review when the sheet is done.
So Sorceress gains greater magic power when in possession of the intelligent Grimoire.
It is actually her casting the spells correct not the sentient book? If so I dont really see an issue. Though I might suggest the Restricted Feat as it would seem that some one would need some arcane knowledge to use the book.
I did note that you have autofire on an area effect, normally these are incompatible.
I did propose we use Targeted Area rules awhile ago but recieved no feedback.
That would allow the usage of Autofire. The thread is
here. I invite any and all that have an opinion to discuss it there.
